I recently purchased a 2ed hand TRG 22 from a store via online. The gun is in very good condition but the the picatinny rail was installed backwards. As a result only 3 screws and two studs are holding the rail down. Who ever installed the rail is a complete clown as he stripped the hell out of the flat head screws that fasten the rail to the receiver. As a result, I cannot undo two of them (the ones on each end of the rail), but they are really Fn tight. The pegs appear to be at least a light interference fit but I can't be sure since I didn't install the rail

I actually like the position of rail as is. If it was installed other way around, it would extend past the receiver and hang above the barrel, far too forward for my taste.

Do you think that with the 3 screws, and 2 pegs, the rail should hold zero?

Shoot it you will find out. Your really fked if its a 20 min rail. I had a screw break off in my action on my rem ti, a good gunsmith charged me 40 bucks and got it out. It took him 2 weeks because he said he had to work himself up to it. he would put it in the vice, pull the drill press down, tell himself "no" put it away and try another day till he felt he was up to it lol. but ya all BS aside i feel your pain. That sucks bro
 
Crazy story about the gunsmith.

I've already sourced some replacement screws and a screw extractor that will fit a M3 or (#5, #6) screw. I also have a very small drill bit to make a pilot hole. But getting a screw out is quite tricky. I know I can always drill it out and re-tap the receiver, but I really don't want to modify a 4g gun.
 
If there is loc tight holding the screws in, maybe try taking a soldering iron and touching it to the screw. Should heat up the screw and break the loc tight. As well, heating the screw and letting it cool (and repeating a few times) could work the screw loose.

ETA

You will have to hold it for a few min. per screw probably, as even blue loc tight has I think ~300 degree "breaking" temp.
 
I have some good news. My friend took his dremel and a very fine cutting bit and re-cut the flat head slots in the screw head. We were able to get those screws out! I've already sourced some replacements, some even locally. Thanks for all the replies.

And to the person who originally mounted this rail: You are an Fn idiot. Learn to use a screwdriver, clown.
 
Go to a good machine shop for some of your work. Many of them can do great work in a short time. I have done this many times because there are not always gunsmith's available in the area.
